The way this sounds is that you are more concerned about politics as in people who take party positions and may feel excluded as a group when the majority of the community takes a different position. This is a slightly different issue i.e. party politics, and I think it is fine/a good thing, but it is also important to distinguish the two. This should essentially be under the same umbrella as personal attacks, as they are essentially the same thing.
There are a ton of other sites where you can follow and debate politics all you want.
I'm starting to stick my nose into local politics here in Bend, Oregon, but there's no reason I need to talk about it on HN. I'm ok with compartmentalizing things: HN for tech/startups/'interesting things', and other sites for other things. I love bike racing, too, and feel that it's the best sport in the world, but I see no need to introduce bike racing articles here.
But where do you draw the line of what is 'politics' and what is 'cool nerdy tech stuff'?
Is a breakdown of 538's method of poll aggregation too politically charged, even if there's a perfectly good overlap of math and statistics?
If Trump makes an out-of-left-field statement about repatriating corporate money, are we prohibited from talking about how it will affect Apple?
A blanket ban of 'political threads and topics' seem harsh, even if just for a week. I personally haven't found the political content on this site to be out of bounds, considering the monumental political upheavals we've been witnessing over the past year.
Politics is about how resources are allocated in society and can often be a very effective solution to problems.
